In this activity, children use common craft materials and ultraviolet (UV)-sensitive beads to construct a person (or dog or imaginary creature). They use sunscreen, foil, paper, and more to test materials that might protect UV Kid from being exposed...(View More) to too much UV radiation. Includes background for facilitators. This activity is part of the "Explore!" series of activities designed to engage children in space and planetary science in libraries and informal learning environments.(View Less)

This is an activity about ultraviolet light. Learners will make ultraviolet light detector bracelets and use them to experiment with artificial light and sunlight. Then, they experiment with various sun-blocking materials to see how such materials...(View More) impact the beads' absorption of ultraviolet light. Special UV detecting beads are required for this activity. This is Activity 3 of the Sun As a Star afterschool curriculum.(View Less)

This is an activity about modeling the apparent motion of the Sun as seen from Earth. Learners will use a flashlight, toothpick, and styrofoam model Sun to mimic the relative shadow motion produced by a sundial. The activity will help learners...(View More) understand that because the Earth rotates from West to East, the Sun appears to rise in the East and set in the West. This is Activity 6 of the Sun As a Star afterschool curriculum.(View Less)

This is an activity about how light travels. Learners will perform two experiments. The first explores blocking light to create shadows. The second asks learners to use mirrors to figure out that light travels in a straight line. This is Activity 4...(View More) of the Sun As a Star afterschool curriculum. This activity requires use of a room that can be darkened.(View Less)
